CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 396,032, dated. January 8, 1889.

Application filed July 28, 1888.

To all whom it may concern.-

Be it known that I, ROBERT H. DOWLING, a citizen of the United States, and a resident of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Car-Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and shows a top view of two draw heads, the shanks being partly broken off. Fig. 2 is a vertical section. Fig. 3 is a top view of the bottom of the drawhead. Fig. at is a bottom view of the top portion of the draw-head. Figs. 5 and 6 show the locking-pin and the coupling-jaw. Figs. 7 and 8 are details.

The invention relates to improvements in car-couplings; and it consists in the construction and novel crmildnation of parts, as hereinafter set forth.

Referring to the drawings, A designates the draw-head, and B the shank thereof. The draw-head and shank are preferably made in two longitudinal sections, as shown at a a. The front face of the draw-head is provided on one side with the forwardly-projecting portion 1), and on the opposite side with the forwardly-projecting bearing-lugs I). A recess, 0, extends inwardly from the front face of the draw-head and has a curved rear wall, 0, which extends around one side of the drawhead and forms the bearing-wall c for the shank of the coupling-jaw, hereinafter described. The inner faces of the lugs Z) are provided with the hub or trunnion-bearings D.

a curved way, (7, between the hub and the recess-wall forms the shoulders d.

The end or face of each hub is on a plane 1 with the adjacent wall of the recess 0, so that Serial No. 281,293. (No model.)

which a curved lug on the shank of the coupling-jaw slides.

F is the coupling-jaw, having the transversely-reduced shank portion G, which stands at right angles to the jaw and normally moves within the recess A curved rib, f, on the shank is designed to engage the trunnion D, and when the jaw is opened the rib f moves in the curved way (1 and bears against the shoulder d.

The curved lug g on the lower edge of the end of the shank is designed to move in the curved way 6.

By this construction of ribs, lugs, and shoulders the locking-jaw is firmly braced against the shock incident upon. coupling cars, and the said jaw is also prevented from being pulled out of its seat.

A vertical opening, is provided through the draw-head and shank for the reception of the round locking-bolt H. To prevent the bolt from turning in the opening, a guard-rib, h, is provided thereon, which engages a groove, h, at one side of the opening.

The lower end of the locking-bolt is beveled at one side, as shown at i, so that when the shank of the jaw is forced inwardly the slightly-beveled edge L. strikes the bevel t and forces the bolt upwardly, which falls back into the opening of the shank when the said shank is at its limit of turn, thus automatically locking the jaw.

It is my design, to operate or raise thelocking-bolt by means of a lever extending to the outer side of the car; but as said lever-connection is not claimed in the present case it is not deemed necessary to show or describe it.

Having described my inventionavhatl claim is 1. The combination of the draw-head having the recess 0, the hubs forming the curved way (I, and the shoulder (Z', the coupling-jaw having the shank provided with the curved ribs f to engage the hubs, and the lockingbolt having the guard thereon, substantially as specified.

2. The combination of the draw-head having the recess, the curved rear wall and the 5 111g having the beveled curved rib E, the hubs ii'orming the curved way and the shoulder, the coupling-jaw having the shank portion at right angles thereto, provided with the curved lug, the bolt-openf, and the locking-bolt having the guard and The beveled end, substantially as specified.

edge, the curved rib In testimony whereof I affix my signature in presence of two Witnesses.
